How far are we from emigrating to Mars?

Human migration to Mars, human transformation of Mars and Mars colonization are actually two different concepts.

Moving to Mars means that all human beings have moved from the earth to live on Mars, while the transformation and colonization of Mars only means that human beings have the technology to land on Mars and gradually build Mars into a planet more similar to the earth's environment. However, this is far from the real survival of human beings on Mars, and it will take a long time for human beings to survive year after year as they do on Earth.

positional information

It is about 55 million kilometers away from the earth, and the farthest distance is over 400 million kilometers. Close contact between them occurs about once every 15 years. In 1988, the distance between Mars and the earth once reached about 58.8 million kilometers, but in 20 18, the distance between them will reach 57.6 million kilometers. But on August 27th, 2003, the distance between Mars and the Earth was only about 55.76 million kilometers, the latest time in 60,000 years.

However, according to astronomers' calculations, during the 800 years from 1600 to 2400, the distance between Mars and the Earth can only rank third. According to the calculation results, by September 2, 2366, the distance between them was about 557 10000 km.

By August 28, 2287, the two will be closer, with a distance of about 55.69 million kilometers.

Generally speaking, the year when Mars is close to the Earth is the best time to land on Mars and observe it on the ground.
